TITLE OF THE INVENTION
EXTENDABLE HEATER
FIELD OF THE INVENTION
The present invention relates to a heater. More
specifically, the present invention is concerned with an extendable
heater mountable to a wall.
BACKGROUND OF THE INVENTION
Radiant heaters are well known and used to provide
heat to selected areas of a given space. These heaters may be used
to heat spaces such as workshops, patios, terraces and the like. Some
of the conventional portable heaters include a flat platform to be placed
on the floor of the given space and having a leg upstanding therefrom,
the leg carries a heater or heater-head on its top portion for
transmitting radiated heat to the selected area. Other heaters may be
mounted to the ceiling, still others may be fixedly mounted to a wall
surface.
A drawback of the prior art heaters is that they often
direct heat to a limited area. In the case of portable heaters, the leg
and platform arrangement limits the space surrounding the heater-head
hence, not all objects that are to be heated can be brought in close
proximity to he heater-head. Hence, these heaters must be placed
close to the area to be heated.
There thus remains a need to provide a heater that
can transmit heat to a greater area.

DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to the appended drawings preferred
embodiments of the present invention will be described herein.
Figure 1 shows a first embodiment of an extendable
heater 10 comprising a wall-engaging member 12, an extendable
member 14 and a heater-head 16.
As shown, the extendable member 14 consists of an
extendable arm provided between the wall-engaging member 12 and
the heater head 16.
The wall-engaging member 12 is designed to be
mounted to a wall surface 20.
CA 02363749 2001-11-23
6
In the embodiment of Figures 1 to 4, the wall-
engaging member 12 has a wall-engaging portion in the form of body
24 and an arm-receiving portion in the form of a generally U-shaped
bracket 26 mounted to the body 24.
The bracket 26 includes first and second arms 28 and
30 each having an aperture (not shown). The bracket 26 is thus
configured to receive the extendable arm 14 as will be explained
below.
The body 24 is a large rectangular piece that can be
made of metal or any other suitable material.
The extendable arm 14 has an accordion like
structure providing it with the ability to extend and retract. The
extendable arm 14 includes proximate and distal ends 32 and 34,
respectively and first and second sides 36 and 38, respectively.
The proximate end 32 is advantageously pivotally
mounted to the bracket 26 of the wall-engaging member 12 while the
heater-head 16 is pivotally mounted to the distal end 34.
The extendable arm 14 includes a pivot joint 40 that
divides the arm 14 into arm sections such as proximate and distal arm
sections 42 and 44, respectively. Hence, the arm sections 42 and 44
are pivotally interconnected at the pivot joint 40 with the proximate arm
section 42 being mounted to the wall-engaging member 12 and the
distal arm section being mounted to the heater-head 16.
Each arm section 42 and 44 includes a pair of
substantially parallel and interconnected longitudinal members.
CA 02363749 2001-11-23
7
More specifically, the proximate arm section 42
includes a pair of similar longitudinal members 46 and 48,
interconnected at the proximate end 32 (as will be discussed below)
and at joint 40. A top member or cover 50 (see also Figures 2, 3 and
4) is mounted to the top edges 52 of members 46 and 48. This top
cover 50 also stabilizes members 46 and 48. As will be explained
further below, members 46 and 48 include respective grooves 54 near
the proximal end 32.
As shown in Figure 1, the distal arm section 44
includes a pair of similar longitudinal members 56 and 58. The distal
section members 56 and 58 are interconnected at joint 40 and at the
distal end 34 (as will be discussed below). Furthermore, members 56
and 58 are interconnected by a top member consisting of a strip
member 60 at their top edges 52 to stabilize members 56 and 58.
As will be discussed below the longitudinal members
46, 48, 56 and 58 have a curved configuration. Also, each member of
a pair of longitudinal members is on a respective arm side 36 and 38.
Each member 46, 48, 56 and 58 has respective first and second ends
62 and 64, respectively, with each end 62 and 64 having a respective
aperture (as will be discussed below). These longitudinal members
are made of a metallic, plastic or other strong and durable material.
The distal end 32 includes a pivot member such as
pivot rod 66 inserted in the apertures of the bracket 26 and of the
members 46 and 48. In the example shown here, the pivot rod 66
hingeably connects the proximate end 32 to the bracket 26.
Specifically, the first end 62 of member 46 is mounted to the first
bracket arm 28 with their respective apertures being aligned so as to
be hinged together by the pivot rod 66. Similarly, the first end 62 of
CA 02363749 2001-11-23
8
member 48 is mounted to the second bracket arm 30 with their
respective apertures being aligned so as to be hinged together by the
pivot rod 66. In this way, the proximate end 32 may be pivoted about a
pivot axis defined by pivot rod 66. Hence, the proximate end 32 may
be considered a pivot joint.
The pivot joint 40 includes a pivot member in the form
of a pivot rod 70.
Specifically, pivot joint 40 is formed by the second
ends 64 of distal arm section 42 being mounted to the first end 62 of
distal arm section 44 with their respective apertures being aligned so
as to be hinged together by the pivot rod 70.
In this way, the proximate and distal arm sections 42
and 44 are pivotable about a pivot axis defined by pivot rod 70.
The heater-head is shown pivotally mounted to the
distal end 34. Hence, the wall-engaging member 12 and the
extendable arm 14 may be considered as a support for the heater-head
16.
In the non-imitative example shown in Figures 1 to 4,
the heater-head 16 has a generally longitudinal configuration and
includes a housing 78 carrying heating elements 80.
The housing 78 is formed of two longitudinal
members 82 and 84, each at a respective arm side 36 and 38, and a
frontal member 86. The longitudinal members 82 and 84 are similar to
longitudinal members 46, 48, 56 and 58 and as such have respective
first and second ends 62 and 64 as well as a curved configuration. The
first ends of members 82 and 84 have respective aperture (not shown)
CA 02363749 2001-11-23
9
which act as arm-receiving portions. Longitudinal members 82 and 84
are joined together at their second ends 64 via the frontal member 86,
mounted therebetween. A top member or cover 87 is also mounted
between members 82 and 84 at their top edges 52. In this way,
members 82, 84, 86 and 87 enclose the heating elements 80.
The distal end 34 includes a pivot member in the form
of a pivot rod 88. Specifically, the second ends 64 of the distal arm
section 44 is so mounted to the first end 62 of the heater head 16 as to
be hinged together by the pivot rod 88. In this way, the heater-head 16
and the distal arm section 44 are pivotable about a pivot axis defined
by the pivot rod 88. Hence, the distal end 34 may be considered a
pivot joint.
It is to be noted that the rod 66 is fixedly mounted to
the proximate end of the arm section 42 and rotatably mounted to the
bracket 26; the rod 70 is fixedly mounted to the proximate end of the
arm section 44 and rotatably mounted to the arm section 42; and the
rod 88 is fixedly mounted to the proximate end of the hater head 16and
rotatably mounted to the arm section 44.
As shown, each pivot joint 32, 34 and 40 is
advantageously provided with a respective actuating assembly 90.
Turning to Figure 4, each actuating assembly 90
includes a housing 92 in which an actuating mechanism 94 is mounted
and a pivot key 96.
The actuating mechanism 94 includes a worm gear
100 and a pinion gear 102 in mutual interterence engagement. The
pivot key 96 is mounted to the worm gear 100 by way of a bolt
assembly 104, for example, so that rotation of the ring 96 causes
CA 02363749 2001-11-23
rotation of the gear 100. Similarly, the pinion gear 102 is so mounted
to a respective pivot rod, such as pivot rod 70 in this illustrated
example, that rotation of the pinion 102 causes rotation of the pivot rod.
The pivot key 96 is provided in the form of a ring to
5 receive, for example, a complementary hook member 105 of a pivot
shaft assembly 106 (see Figure 1).
This pivot shaft assembly 106 includes a pivot shaft
107 having the hook member 105 on its distal end and a handle 108 at
its proximate end. The handle may be a mechanical handle that is
10 manually operated or a motorized handle than can spin the shaft 107
by pressing a switch (not shown), for example.
With reference to Figures 1 to 4, the operation of the
extendable heater 10 will now be described.
The arm 14 is moveable by pivoting its arm sections
42 and 44 about pivot joint 40.
In this respect, the heater-head 16 is reciprocally
moveable between a fully retracted position illustrated in Figure 2 and a
fully extended position illustrated in Figure 1.
In the fully retracted first position shown in Figure 2,
the extendable arm 14 is fully retracted or folded and the heater-head
16 is in close proximity to the wall-engaging member 12. Usually the
heater 10 is in this retracted position when not in use. This position
along with the configuration of the heater-head housing 78 is
convenient since the heating elements 80 are boxed therein and, as
will be described, the housing 78 is boxed within the distal arm section
44. In this way, the heating elements 70 are protected from adverse
CA 02363749 2001-11-23
11
weather conditions, vandalism and the like. Furthermore, a box
container (not shown) may be mounted to the wall-engaging member
12 or wall 20 to fully surround the heater 10 and may have a front door
(not shown) to close in the extendable heater 10. This container may
also be provided with a pad or combination lock to secure the heater
therein. An alarm system attached to the locking may also be
provided.
In the fully extended position shown in Figure 1, the
extendable arm 14 is fully extended and the heater-head 16 is at the
10 greatest possible distance away from the wall-engaging member 12.
Of course, the foregoing distance will vary in accordance with the
configuration and length of arm 14, which is dependent on the length of
the longitudinal members and the number of arm sections.
In order to move the heater-head 16 between the first
and second positions the user will pivot the pivot joints 32, 34 and 40
about their respective pivot rods 66, 70 and 88. The user utilizes the
pivot shaft assembly 106 to turn the pivoting key 96 on a given pivot
joint 32, 34 and 40.
With particular reference to Figure 4 the user engages
the pivot key 96 with the hook member 105 of the pivot shaft assembly
106. Using the handle 108 the user manually or by way of motor turns
the shaft 107 about its vertical axis Y causing the key 96 to turn
therewith. This causes the worm gear 100 to also turn about the Y axis
so as to act on the pinion gear 102 which will turn along with rod 70 (in
the specific example of Figure 4) about the pivot axis Z defined by pivot
rod 70. Of course, the foregoing is applicable to the pivoting of rods 66
and 88.
CA 02363749 2001-11-23
12
Shaft 105 can either be turned in clockwise or
counter-clockwise directions as respectively shown by arrows A and B
in Figure 1. This depends on whether the user wishes to ultimately
pivot a given rod 66, 70 or 88 in a forward or backward direction as
respectively shown by arrows C and D in Figure 2. Therefore, in the
non-limiting example shown here, turning a given pivot key 96 in the
clockwise direction A, results in pivoting a respective pivot rod 66, 70 or
88 in the backward direction D, causing the extension of the heater.
Alternatively, turning a given pivot key 96 in the counter-clockwise
direction B, results in pivoting a given pivot rod 66, 70 or 88 in the
forward direction C, causing the retraction of the heater. It should be
noted that the foregoing forward and backward pivoting movements of
rods 66, 70 and 88 are dependant on the configuration of the gears
100 and 102 and their mutual interaction.
It will easily be understood by one skilled in the art
that the rods 66, 70 and 88 are actuated by respective actuating
assemblies 90 in sequence to uncoil the extendable heater 10 and in
reverse sequence to coil the heater 10.
It will also be noted that the grooves 54 are provided
to allow the actuating assembly 90 associated with the pivot rod 88
therein in the retracted positions (see figures 2 and 3).
The proximate arm section members 46 and 48 are
wide and long enough to box in both arm section 44 and the heater-
head 16. The curved configuration of the longitudinal members 46, 48,
56, 58, 82 and 44 as well as the space between each pair of
longitudinal members provide for the heater 10 to be easily folded or
recoiled.
CA 02363749 2001-11-23
13
In order to maintain the present extendable heater 10
in position, such as the ones depicted in Figures 1 or 3, tension rings
(not shown) may be mounted to each pivot rod 32, 34 and 40 and at
each of the pivot rod ends. Of course other ways of maintaining the
pivot joints 32, 34 and 40 in position may also be contemplated within
the scope of the present invention.
It is also to be noted that while the appended
drawings show the heater head 16 in a position generally parallel to the
ground, the heater head 16 may be positioned in other suitable and
desirable positions. The heater-head may be pivoted about the distal
end 34 to radiate heat in different directions.
With respect to the above-described embodiment,
what follows is a brief description of some alternative features that are
included, without limitation, within the scope of the present invention.
Referring to the wall-engaging member 12, it should
be noted that the body 24 may be provided in a variety of suitable
shapes. Furthermore, the wall-engaging member 12 may include only
the bracket 26. In this case, it is the bracket that is directly mounted to
the wall surface 20. Also, proximate end 32 may be directly mounted
to the wall surface 20 and in this case the proximate end 32 may be
considered to be a wall-engaging member.
With respect to the arm 14, it should be noted that a
greater number of joints will provide for a greater number of arm
sections. Furthermore, members 56 and 58 are interconnected by one
or more top members of strips 60 at their top edges 52. In fact this
strip 60 may cover the whole top length of arm section 44. Of course, it
CA 02363749 2001-11-23
14
may be contemplated that the arm 14 does not include a cover 50, nor
a strip 60.
The arm 14 may be pivotally mounted to the wall
engaging member 12 by a variety of suitable ways known to the skilled
artisan.
With reference to the heater-head 16, it is to be
understood that it may be provided in a wide variety of suitable
configurations and sizes. The heating elements 80 may be mounted to
the housing 68 by a variety of conventional ways. The heating
elements 70 may include a variety of types known in the art.
The heater-head 16 may include of variety of
conventional heaters that are mounted or mountable to the distal end
30. Of course, the heater-head 16 may be pivotally mounted to the
distal end 34 by a variety of conventional ways.
In one embodiment, the heater-head may be a gas
heater. In this way, the heater-head 16 may be connected to a gas
supply (not shown) via a flexible gas pipe or tube (not shown). In one
example, this tube may be connected along the longitudinal members
via brackets. The gas supply may be provided with a control such as a
knob, a lever, a switch and the like to control the flow of gas being sent
to the heater-head 16.
In another embodiment, the heater-head 16 may be
an electric heater. In this way, heater-head 16 may be connected to an
electric power supply (not shown) via a wire (not shown). For example,
the wire may be connected along the longitudinal members via
brackets; the wire may then be connected to a switch assembly (not
shown) which can be mounted to or housed in the wall-engaging
CA 02363749 2001-11-23
member 12, or mounted to or housed in the wall 20. In another non-
illustrated example, arm sections 40, may comprise tubular sections for
fitting the wire therein.
Of course, other numerous ways, known in the art, to
5 power the heater-head 16 may also be contemplated within the scope
of the present invention.
With respect to the pivot assemblies 90, other types
of pivot assemblies known in the art may also be contemplated within
the scope of the invention such as a universal joint assembly or even a
10 motorized actuating assembly to give just two examples. In the case of
motorized pivot assemblies each assembly at each joint 32, 34 and 40
may be interconnected to a wire which is connected to a power source
that may be mounted to the wall-engaging member 12 or mounted or
even housed within the wall 20, a power switch (not shown) can be
15 used to operate the motorized pivot assemblies, simultaneously or in
sequence.
Turning now to Figures 5 to 9 another embodiment of
the present invention will be described.
Figure 5 shows an extendable heater 110 comprising
a wall-engaging member 112, an extendable member 114 and a
heater-head 116.
Again, the extendable member is extendable arm 114
provided between the wall-engaging member 112 and the heater head
16.
The wall engaging member 112 includes a wall-
engaging portion in the form of a wall-engaging side 118 for engaging a
CA 02363749 2001-11-23
16
wall surface 120 (see Figure 9) such as the outer house wall in a patio
setting 122 as shown in Figure 9, for example. In this example, the
wall-engaging member 112 has inner and outer body portions 124 and
126, respectively. The second or outer body portion 126 is configured
to receive the extendable arm 114, as will be explained below.
The extendable arm 114 includes proximate and
distal ends 128 and 130, respectively and first and second sides 132
and 134, respectively.
The proximate end 128 is pivotally mounted to the
wall-engaging member 112 and the heater-head 116 is pivotally
mounted to the distal end 130.
The extendable accordion arm 114 includes two pivot
joints, 136 and 138 that divide the arm 114 into arm sections, such as
proximate, medial and distal arm sections 140, 142 and 144,
respectively.
The extendable accordion arm 114 has at least two
arm sections interconnected via a pivot joint with one arm section being
mounted to the wall-engaging member 112, such as the proximate arm
section 140 in Figure 5, and another arm section being mounted to the
heater-head 116, such as the distal arm section 144 in Figure 6.
Each arm section 140, 142 and 144 includes a pair of
substantially parallel and interconnected longitudinal members. More
specifically, the proximate arm section 140 includes a pair of similar
longitudinal members 146 and 148; the medial arm section 142
includes a pair of similar longitudinal members 150 and 152; and the
distal arm section 144 includes a pair of similar longitudinal members
154 and 156.
CA 02363749 2001-11-23
17
Each member of a pair of longitudinal members is on
a respective arm side 132 and 134. The proximate section members
146 and 148 are interconnected at the proximate end 128 (as will be
discussed below) and at pivot joint 136; the medial section members
150 and 152 are interconnected at pivot joints 136 and 138; and the
distal section members 154 and 156 are interconnected at joint 138
and are interconnected at the distal end 130 (as will be discussed
below). Each member 146, 148, 150, 152, 154, and 156 has
respective first 158 and second 160 ends with each end 158 and 160
having a respective aperture (not shown).
As will be explained below the proximate arm section
140 is hingeably connected to the medial arm section 142 at pivot joint
136 and the medial arm section 142 is hingeably connected to the
distal arm section 144 at pivot joint 138.
Each pivot joint 136 and 138 includes respective pivot
members such as pivot rods 162 and 164 respectively. Each pivot rod
162 and 164 has first and second ends 166 and 168 at each arm side
132 and 134 respectively.
Specifically, pivot joint 136 is formed by the second
end 160 of member 146 being mounted to the first end 158 of member
150 with their respective apertures being aligned so as to be hinged
together by the first end 166 of pivot rod 162. Similarly, the second
end 160 of member 148 is mounted to the first end 158 of member 152
with their respective apertures being aligned so as to be hinged by the
second end 168 of pivot rod 162.
The pivot joint 138 is constructed in the same fashion
hence, the second end 160 of member 150 is mounted to the first end
CA 02363749 2001-11-23
18
158 of member 154 with their respective apertures being aligned so as
to be hinged together by the first end 166 of pivot rod 164. As before,
second end 160 of member 152 is mounted to the first end 158 of
member 156 with their respective apertures being aligned so as to be
hinged together by the second end 168 of pivot rod 164.
Of course, it is within the scope of the present
invention that pivot joints 136 and 138 may be constructed in other
conventional and suitable ways as is known in the art.
The proximate end 128 is pivotally mounted to the
wall-engaging member 112.
In this respect, the distal end 128 includes a pivot
member such as pivot rod (not shown) which is similar to pivot rods
162 and 164. This pivot rod is journalled in the inner body portion 126
of the wall-engaging member 112 through an arm-receiving portion
such as a longitudinal aperture (not shown) perforating the inner body
portion. The first 166 and second (not shown) ends of the pivot rod
protrude the longitudinal aperture and are respectively pivotally
mounted the first ends 158 the of longitudinal members 146 and 148
through their respective apertures (the second end of member 148 is
not shown) hence, hinging the proximate end 128 to the inner body
portion 126. In this way, the proximate end 128 is pivotable about a
pivot axis defined by this above-mentioned pivot rod.
As before, the heater-head 116 may be a
conventional gas or electric heater being mounted or mountable to the
distal end 130.
In the non-imitative example shown here, heater-head
116 includes a housing 172 and a heat-transmitting underside 174 for
CA 02363749 2001-11-23
19
transmitting heat to an object which is desired to be heated. Heat may
be provided by a variety of heating elements (not shown).
As aforementioned, the heater-head 116 is pivotally
mounted to the distal end 130.
In this respect, the distal end 130 includes a pivot
member such as pivot rod 176 similar to pivot rods 162, 164 and 170
and also having first and second ends 166 and 168, respectively. The
heater-head 116 includes pivot member receiving members such as
first 178 and second 180 bracket members. Each bracket member 178
and 180 includes a respective aperture (not shown). Bracket members
178 and 180 are respectively mounted to the second ends 160 of
longitudinal members 154 and 156 with their respective apertures
aligned so as to be hinged together by the first 166 and second 168
ends of pivot rod 176 respectively. In this way, the heater-head 116
and the proximal arm section 144 are pivotable about a pivot axis
defined by the pivot rod 176.
With reference to Figures 6, 7, 8 and 9 the operation
of the extendable heater 110 or support for heater a heater-head 116
will be described.
The accordion arm 114 is moveable by pivoting its
arm sections 140, 142 and 144 about pivot joints 128, 137, 138 and
130. In this respect, the heater-head 116 is reciprocally moveable
between a fully retracted position shown in Figure 6 and a fully
extended position shown in Figures 8.
In the fully retracted position, shown in Figure 6, the
extendable accordion arm 114 is fully retracted or folded and the
heater-head 116 is in close proximity to the wall-engaging member

112. Again here, this position is convenient when the heater 110 is not
in use since the heater is in a fully retracted or recoiled position, which
protects the heat projecting underside 174.
In the fully extended position shown in Figure 8, the
5 extendable accordion arm 114 is fully extended and the heater-head
116 is in the greatest possible distance away from the wall-engaging
member 112. The foregoing distance will vary in accordance with the
configuration and length of the extendable arm 114.
The user can move the heater-head 116 between the
10 first and second positions by pulling or pushing the arm 114 so as to
position arm 114 in a particular desired position, such as a partially
retracted position as shown in Figure 7 or the position shown in Figure
9. Of course, a handle (not shown) may be provided on the arm 114 or
heater-head 116 in order to move the heater-head 116. It must be
15 noted that the pivotable connections at joints 136 and 138 and at
proximate and distal ends 138 and 140 are provided with sufficient
tension so as to maintain the extendable arm 114 and the heater-head
116 in a desired position.
Again here, it is also to be noted that while the
20 appended drawings show the heater head 116 in a position generally
parallel to the ground, the heater head 116 may be positioned in other
suitable and desirable positions. The heater-head may be pivoted
about the distal end 130 to radiate heat in different directions.
When is use and with particular reference to Figure 9,
the present extendable heater 110 or support for a heater 116 is
mounted to a wall 120, by fixedly engaging the wall-engaging member
112 to the wall 120 by a variety of conventional ways. Advantageously,
CA 02363749 2001-11-23
21
the extendable heater 110 is placed adequately high on the wall 120 so
as to transmit heat, as shown by schematic waves 182, to a desired
and specific area such as a table and chair assembly 184 for example,
on a patio 122 or a terrace and the like.
In the example shown here, the heater-head 116 is
positioned in a somewhat distant position from the wall-engaging
member 112. The heater-head 116 will be moved depending on
whether the user wishes to bring it closer or further from the area which
is desired to be heated, such as the chair and table assembly 184.
An advantage of the present invention is that the
extendable heater 10 or 110 disclosed herein can be fixed to a wall
surface yet can be brought closer or pushed further away from the area
which is desired to be heated.
